BIOSF_UPLOAD ($C00546): Upload data to DRAM

BIOS_UPSRC      (32bit): Source (Long)
BIOS_UPDEST     (32bit): Destination (Long)
BIOS_UPSIZE     (32bit): Size (Long)
BIOS_UPZONE     $10FEDA (8bit):  Zone (Byte, 0=PRG, 1=FIX, 2=SPR, 3=Z80, 4=PCM, 5=PAT)
BIOS_UPBANK     (8bit):  Bank (Byte)

For FIX, Z80 (, PAT ?) and PCM upload, the destination has to be multiplied by 2 (8bit busses). The SPR bank size is 1MiB (4 banks), PCM bank size is 512KiB (4 banks). The other zones aren't banked.

BIOS_UPDEST (and BIOS_UPSRC ?) is incremented by the size upon completion, which allows to do multiple consecutive uploads.

Steps

  • $FF0004.w and $10FD80 are pushed
  • $FF0004.w = 1
  • $10FD80=0, system mode
  • BIOS_UPZONE anded with $F
  • Jump table
  • Subrout1
  • Copydata
  • BIOS_UPZONE anded with $F
  • Jump table
  • Subrout2
  • Restore $10FD80.w and $FF0004.w
